Rihanna has announced the cities she will be travelling to on her mini '777' tour in promotion for the release of her next studio album Unapologetic.

The 'Diamonds' songstress will be heading to seven countries across seven days, bringing with her a selected group of fans and journalists on the tour bus, in the lead up to the release of her seventh studio album on November 19.

"I am so excited about the '777' tour. We are turning this jumbo jet into our tour bus," Rihanna said in a press release.

"We are practically living on this thing for a week: sleeping, partying all together. Me, my fans, the press… it's going to be a wild ride."

"I wanted it to be a rock n' roll adventure, and I think when it's over it will be the coolest thing I've ever done. I'm that excited about it."

While she has revealed the cities she will be visiting, RiRi has decided to announce the gig venues when she touches down in each country.

The 24-year-old also sent out a warning on Twitter that those lucky enough to be invited onto the 'flying tour bus' may not be so lucky after all, revealing there may be some naughty antics. "#777 tour!!! This is really going down huh?!!" RiRi tweeted yesterday.

"This was once a random idea thrown out in the brainstorm… coincidentally, on a plane! Whoever is getting on my flying tour bus with us, Good luck!!"

Unapologetic features the lead single 'Diamonds' and her Chris Brown collaboration 'Nobodies Business.'
